Tomei Rb25 Solid Lifter Kit

[donut_kng]

Howdy,

After having my forged 25/30 running in my R33 for almost 2 years now, I would from time to time hear the odd 'single lifter noise'.

The engine still has hydraulic lifters, all of which have been replaced as a part of the build although now after a bit of time I still get the odd lifter tapping away, after giving it a hard time up the mountains, to which after cruising a bit it would then go away, although now as of late, it is now tapping/clicking 24/7.

I usually run Valvoline acing formula 50 oil which is a 25/60 - thinking this was the issue I experimented with a Penrite 15/30 - it actually made the noise louder. Also the hotter the engine running the noisier it gets - no surprises here.

The car pulls about 500kw on 30psi E85 although mostly driven on around 20psi on pump, and never limiter bashed. The RPM only is set to 7000 anyways so nothing huge compared to standard I would have thought.

Have been looking at this kit http://www.ebay.com.au/itm/Tomei-Forged-Solid-Lifters-Kit-for-Nissan-R33-R32-RB25-RB20-VG30-/360524217648 and http://www.nengun.com/tomei/valve-lifters which I cant seem to find much info on any successful applications - has anyone used this?

The head already has sold type cams just need to make a call on which way to go with the lifters or if there is any other option available to me? Or anywhere in Sydney that could help me out?

I don't intend to push any more power out of the car and will happily turn the boost down after I sort this out if that's what it takes - as all that power out of 2 wheels isn't essential!
